本文通过对八尺门海堤两侧海域表层沉积物和柱状沉积物的分析、不同时期的海图和实测水深数据对比,对八尺门海堤两侧海域沉积环境及冲淤变化进行了分析.研究结果表明:八尺门海域表层沉积物以黏土质粉砂为主,沉积物类型趋于单一;柱状沉积物210pb活度未呈指数型下降,表明沉积物受到扰动影响,沉积速率表明八尺门海堤两侧海域的沉积速率随时间呈逐渐增大的趋势;八尺门海域总体上为淤积状态,冲淤变化的原因主要为八尺门海堤对东山湾和诏安湾之间水体交换的阻隔,养殖网箱、吊养设施和养殖池塘对海流的阻碍,养殖过程中流失和残余的饵料及养殖

从西沙永乐群岛7个岛礁海域的海水中分离出47株弧菌,将47株菌株进行16S rDNA、HSP60和gyrB扩增,序列在Genebank中进行比对,构建系统发育树.结果 显示利用16S rDNA和HSP60序列比对均无法鉴定弧菌到种.gyrB1和gyrB2引物均只能扩增出6株菌株的目标序列,gyrB3引物能扩增47株菌株的目标序列,且成功构建系统发育树,可鉴定弧菌到种.47株弧菌菌株分属于7个种,鸭公岛弧菌多样性最丰富,可分离到5种;石屿和羚羊礁筐仔沙洲弧菌多样性最低,均只分离到2种.本研究建立了可靠的海洋
2013年至2019年在闽江口进行了11个航次共38个断面的潮间带大型底栖动物调查研究,共发现潮间带生物195种,隶属10个门类,主要以甲壳类、软体动物和多毛类为主.敖江入海口潮间带生物的物种多样性、生物量和丰度均显著高于闽江入海口,且敖江入海口潮间带生物的多样性指数(H\')、均匀度指数(J\')和丰富度指数(D)也均显著高于闽江入海口.闽江口潮间带生物的物种数、丰度和生物量在中、低潮区均显著高于高潮区.闽江入海口潮间带的优势种以小型蟹类为主,敖江入海口潮间带的优势种包括多毛类、软体动物和蟹类,
为研究6月龄斑头鱼形态性状对体质量的影响,采用相关性分析、回归分析和通径分析的方法,对220尾斑头鱼的全长(X1)、体长(X2)、头长(X3)、躯干长(X4)、尾柄长(X5)、尾柄高(X6)、体高(X7)和体宽(X8)8个形态性状和体质量(Y)进行测量和分析.结果 表明,所测量的8个形态性状与体质量的相关性均达到极显著水平(P＜0.01).通径分析表明,体长、体宽、全长、头长和体高是影响体质量的主要形态性状.决定系数显示,体长的单独决定系数最大,为0.299;全长和体长的共同决定系数最大,为0.244;总
